For the love of Seuss: It's shaping up as Pop Culture Day at Thought Balloons. Writing for The Guardian, Michael Rosen examines the life and legacy of Dr. Seuss:

"Many of the books succeed because they represent a response to language that coincides with a young child's discovery of the pluck and knock of words. I've just read Green Eggs and Ham to my three-year-old and an hour later I heard her muttering: 'That Sam-I-am! That Sam-I-am! I do not like that Sam-I-am!'"

The Guardian also has a "Seussentennial" quiz.
